Subject: [PATCH] configure: Fix cross-compilation errors
|
||||
|
||||
AC_RUN_IFELSE does not work when cross-compiling so we need to provide
|
||||
fallback methods for those cases.
|
||||
|
||||
I tried to use constructs that work with Autoconf 2.52.
|
||||
Alas, I wasn't able to generate a working build system with that version.
|
||||
|
||||
Autoconf 2.58 / Automake 1.7.9 is the earliest combo that I could get
|
||||
to work (with and without this patch).
|
||||
Perhaps it's time for a slight bump for the required version numbers?
|
||||
|
||||
Cross-compiles sucessfully against:

||||
riscv64-unknown-linux-gnu
